Definitions

  • the invention relates to a dual-stack optical data storage medium for write-once recording using a focused radiation beam having a wavelength ⁇ of approximately 655 nm and entering through an entrance face of the medium during recording, comprising:
  • An embodiment of an optical recording medium as described in the opening paragraph is known from Japanese Patent Application JP-11066622.
  • DVD Digital Versatile Disk
  • ROM read only
  • R recordable
  • RW rewritable
  • DVD+R DVD-R for recordable and DVD+RW
  • DVD-RW DVD-RAM for rewritable.
  • An issue for both the recordable and rewritable DVD formats is the limited capacity and therefore recording time because only single-stacked media are present with a maximum capacity of 4.7 GB.
  • DVD-Video which is a ROM disk
  • dual layer media with 8.5 GB capacity often referred to as DVD-9
  • DVD-9 dual layer media with 8.5 GB capacity
  • DVD+RW and DVD+R One of the most important concerns for DVD+RW and DVD+R is to obtain backwards compatibility with existing DVD-ROM/DVD-video players. It is expected that dual-layer DVD+R, which is currently being developed, can achieve high compatibility with existing dual-layer DVD-ROM media; an effective reflection from both layers above 18 % and signal modulation of 60 % as demanded by DVD-ROM-DL, has been demonstrated in experiments. Note that the wordings "dual-layer” and “dual-stack” are often used interchangeably. In fact when dual-layer is written actually dual-stack is meant. The same holds for the expressions “single-stack” and "single-layer”.
  • Effective optical reflection means that the reflection is measured as the portion of effective light coming back from the medium when e.g. both stacks L0 and L 1 are present and focusing on L0 and L 1 respectively.
  • the nominal write power for 4X and 8X single-layer media should be considerably below this value, i.e. ⁇ 15 mW for 2.4X, ⁇ 19 mW for 4X and ⁇ 30 mW for 8X. Note that, due to mechanical limitations, the speed-race for DVD will be limited to 16X recording for which the estimated write power is 50 mW.
  • DVD+R-DL The problem with DVD+R-DL is that there is nearly twice as much storage capacity but a limitation in available recording speed. For instance DVD+R single-layer is now recordable at 8X, while DVD+R-DL is limited to 2.4X. It would be very favorable for the acceptance of DVD+R-DL, if the DVD+R-DL can keep pace with the DVD+R single-layer speed-race. The current DVD+R-DL media are too unsensitive to keep up with this speed race due to laser power limitations.
  • optical data storage medium which is characterized in that 0.12 ⁇ R L0 ⁇ 0.18 and 0.12 ⁇ R L1eff ⁇ 0.18.
  • the applicant has found that when the reflection parameters fall in this range a good compromise between signal strength of the read-out written information and recording layer sensitivity is achieved.
  • These effective reflection ranges are acceptable to achieve read-out compatibility in a high percentage of existing DVD-players. Note that, at present, such a reflectivity range is not achievable in a rewritable (RW) dual-stack DVD based on e.g. phase-change technology.
  • the reflection and transmission of L0 stacks is tuned mainly by variation of the thickness d L0M of the semitransparent mirror, e.g. Ag or an Ag-alloy, and to a lesser extend by the absorptivity of the dye.
  • d L0M the semitransparent mirror
  • the write power for L1 in a dual-layer disc will be proportional to (A L1 *T L0 ) -1 .
  • a T L0 of 60 % or more can be achieved when the first recording stack comprises a first reflective layer with a thickness d L0M and an absorption coefficient k L0M and the L0 recording layer has an absorption coefficient k L0R and a thickness d L0R and where (k L0R * d L0R + k L0M * d L0M ) ⁇ 0.08* ⁇ .
  • T L0 is calculated for two different dyes dye 1 and dye 2.
  • the k as a function of the wavelength is shown in Fig. 7.
  • the second recording stack comprises a second reflective layer and the L1 recording layer has an absorption coefficient K L1R and where the intrinsic reflection R L1 of the second recording stack is in the range 0.30 - 0.60 and where 0.075 ⁇ k L1R ⁇ 0.25.
  • a second reflective layer is present at a side of the write-once type L 1 recording layer most remote from the entrance face.
  • the second reflective layer is metallic and has a thickness d LlM ⁇ 25 nm and preferably the thickness of the dye layer d L1R is in the range of 0 ⁇ d L1R ⁇ 3 ⁇ /4n L1R .
  • the latter range is the range of a conventional single stack write once medium.
  • d L1M is lower than 25 nm the reflectivity may become too low.
  • the lower L1 stack of a recordable dual-stack DVD medium should have high reflectivity at the radiation beam wavelength in order to be able to read back recorded data through the above L0 stack.
  • the first reflective layer has a thickness d L0M ⁇ 16 nm, preferably d L0M ⁇ 12 nm and mainly comprises one selected from Ag, Au or Cu.
  • a relatively thin first reflective layer is placed between the dye and the spacer.
  • the first reflective layer serves as a semi-transparent layer to increase the reflectivity.
  • a maximum thickness and suitable material must be specified to keep the transmission of the first metal reflective layer sufficiently high.
  • the metal layer e.g. Ag, Au, Cu, and also Al, or alloys of all thereof, or doped with other elements, can be used.
  • the preferred thickness of the first reflective layer is as specified above.
  • k L0R > 0.025, more preferably > 0.050.
  • k L0R 0.025, more preferably > 0.050.
  • the contribution of the first recording layer thickness (dye) to the total absorption of the L0 stack is rather small.
  • reflection and transmission of L0 are to a large extent determined by the choice of Ag(-alloy) thickness. Therefore, using a dye with a higher absorption will increase the sensitivity of the L0 recording stack, with little adverse effects on the transmission and reflection.
  • the present invention can be applied to all dual layer DVD recordable (R) formats.
  • the dye material of the recording layers intrinsically has a high transmission at the recording wavelength ⁇ .
  • Typical dyes that can be used are cyanine-type, azo-type, squarylium-type, or other organic dye material having the desired properties.
  • guide grooves for guiding the radiation beam may be present in both the L0 and the L1 stack.
  • a guide groove for the L0 stack is normally provided in the substrate closest to the entrance face.
  • a guide groove (G) for L1 is provided in the transparent spacer layer. This embodiment is called type 1.
  • a guide groove (G) for L1 is provided in the substrate. This embodiment is called type 2.
  • a dual-stack optical data storage medium 10 for recording using a focused radiation beam 9, e.g. a laser beam, having a wavelength 655 nm is shown.
  • the laser beam 9 enters through an entrance face 8 of the medium 10 during recording.
  • the first recording stack L0 has an optical reflection value R L0 and an optical transmission value T L0 .
  • the second recording stack L 1 has an optical reflection value R L1 .
  • the optical parameters are all measured at the laser beam wavelength.
  • the first recording stack 6 is present at a position closer to the entrance face 8 than the second recording stack 3.
  • a transparent spacer layer 4 is sandwiched between the recording stacks 3 and 6.
  • the transparent spacer layer 4 has a thickness substantially larger than the depth of focus of the focused radiation beam 9.
  • the stacks are tuned such as to meet the following requirements 0.12 ⁇ R L0 ⁇ 0.18 and 0.12 ⁇ R L1eff ⁇ 0.18, in which R L1eff is the effective reflection from recording stack 3 at the entrance face 8, after double passing through recording stack 6
  • R L0 is substantially equal to R L1eff .
  • the transparent spacer 4 has a thickness of 55 ⁇ m.
  • Optical reflection R L0 of L0 is 15 %
  • transmission T L0 of L0 is 61 %
  • effective reflection R L1eff (through L0) of L1 is 15 %.
  • the L0 stack has a guide groove with a depth of 145 nm and a width of 325 nm (FWHM).
  • the L1 stack has a guide groove G with a depth of 170 nm and a width of 370 nm (FWHM).
  • the guide groove G is provided in the transparent spacer layer 4.
  • Fig. 3 the average jitter versus write power for L0 stacks having different reflection is shown.
  • the average jitter is a measure for the deviation of the position of written marks from their optimum position.
  • the average jitter is minimal at optimum write power. Circles: 7 % reflection, Squares: 9 % reflection, Crosses: 18 % reflection. It is noticeable that over a large range of R L0 values the optimum write power stays remarkably constant.
  • the reflection and transmission of L0 stacks is tuned mainly by variation of the thickness d L0M of the semitransparent mirror, e.g. Ag or a Ag-alloy, and to a lesser extend by the absorptivity k of the dye.
  • the semitransparent mirror e.g. Ag or a Ag-alloy
  • Fig. 5 the theoretical dependence of write power of L1: P L1norm on effective reflection of L0 and L1 is shown.
  • R L1eff R L0
  • P L1norm in a dual-layer disc will be proportional to (A L1 *T L0 ) -1 .
  • Fig. 6 the playability of dual-layer DVD media having reduced reflection level on existing DVD players is shown. Playability is defined as the percentage of existing DVD players that will correctly read the data from the inserted medium.
  • Fig. 7 the absorption coefficient k as a function of ⁇ for two dyes used in DVD+R (DL) is shown.
  • Dye 2 has a larger absorption value k than dye 1.
  • Fig. 8 the calculated reflection, modulation, transmission, and modulation x reflection product for an L0 stack as function of Ag thickness are shown for dye 1 and dye 2.
  • Fig. 9 the transmission T L0 as a function of (k L0R * d L0R + k L0M * d L0M )/ ⁇ is shown.
  • a T L0 of more than 60 % can be achieved when (k L0R * d L0R + k L0M * d L0M )/ ⁇ 0.08.

  • An optical recording stack (L0), optically semi-transparent at the laser wavelength, is applied to a transparent, pre-grooved substrate 7.
  • a transparent spacer layer 4 is attached to the L0 stack.
  • the spacer layer 4 either contains pregrooves (G) for L1 or pregrooves (G) for L1 are mastered into the spacer layer 4 after application to L0.
  • Second recording stack L1 is deposited on the grooved spacer layer 4. Finally, a counter substrate 1 is applied.
